BED-LOUNGE.

SPECIFICATION forming part of Lettersl Patent No. 257,856, dated May 16, 1882.

To all whom it may concern:

Be it known that I, FREDERICK FIsonBncK,

, of Chicago, in' the county of Cook and "State of and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in that class ot lounges described in Letters Patent No. 85,391, granted to William H. Lotz December 29,1868, and reissued May 25,1880, of which, by mesue assignments, I am now the sole proprietor; also, in Letters Patent No. 169,978, granted to me November 16, 1875; and it consists in the application ot' asin'gle spiral spring to such a lounge, that by its tension will counteract the, weight of the upper shell, and thus-assist in lifting such shell for either opening or closing the lounge, and also in a device for adjusting or regulating the tension of such spring to accommodate it to the difference in weight of the various styles of such lounges, to counterbalancethe upper shell of such lounge to any desired extent, or to compensate for any relaxation of the spring by the frequent opening and closing of the same.

In the accompanying drawings, Figure l represents a sectional end view of the lounge, with the shell in a half-way position for either closing or extending thelounge; Fig. 2, a plan ofthe lounge when extended; and Figs. 3, 4, 5, 6, 7, and 8, details of the adjustable spring attachment.

Like letters designate corresponding parts in all the figures.

A denotes the loungebody; B, the shell, which is connected to the body A by linksor arms G-one at each end-each of said arms being connected at one end rigidly to theshatt or rod a, lying at or near the bottom and running lengthwise of the lounge-body. This shaftct is generally made ot' square bar-iron, and the arms O are provided with truunions, that are pivoted in metal boxes secured to the ends of the loungebody, and have square sockets for inserting the ends of shaft a.. rlhe arms C are of such lengths and the pivots so located that when the shell is on the body ofthe lounge Appnanon inea Marcil 17, lesa. (No modell) they allow it to rest snugly in place, with its rear edge close against the back ot' the lounge and its lower edges resting upon the ledge b, and when swung down in front ott1 the body, to hold the shell lirmly up against the sofa, with its rear edge resting' upon the ledge b. Near the front end ot' the lounge I sleeve upon the shat't aan arm, D, having asquare holein its hub, that ts snugly upon such shaft, and an eye in its outward end for coupling the end hook of a spiral spring, E.

A picce,F, of which Figrepresents a lon gitudina-l section and Fig..6 an end view, consists of a circular flange, o, that has a square ssv socket, d,for receiving and guiding the hook G, and has a central hole for admitting the shank of a thumb-screw, H. The squaresock eted portion of this piece F is passed through a corresponding hole-in the back board of the lounge-frame, and its flange cis let into a suitable recess in such board, so as to be tlush with the exterior surface thereof, and is secured thereto by wood-screws. The hook Gr has a square shank that enters the socket d, and is longitudinally bored and tapped to engage with the screw-threaded shank ofthumb-screw H, which enters the hole in llange c ot' piece F.

'Ihe spring E has a hook or loop formed to each end, one end to be coupled with theend of arm D and its opposite end with the hook G. The arm D is secured upon shaft a at a position rectangular to the position ofthe arms O, and in a manner that when the shell B ot" the lounge is swung haltway, so as to balance upon such arms, the springE is not expanded to any extent; but when the shell B is lowered in either direction for closing or opening thc lounge the spring E is expanded in proportion as the weight lo be balanced increases by the arms G acquiring a more horizontal position, thereby neutralizing such Weight and making the operation of lifting such shellaud of lowering it again a very easy one, that requires but very little power and will enable a child` to perform the extending or opening of the lounge. The adjustment for such springs by screw H, or by other suitable means for regulating their tension proportional to the weight to be counterbalanced, is of great importance, since such springs are not made all the exact length, and are not of a uniform temper, be-

IOO

sides Whichloun ges of the above class are made up in different styles, 0i' all kinds of lumber, differing considerably in specific gravity, as Well as of different qualities of upholstering material; also differing considerably in weight. Therefore without such provision l'or adjustment a manufacturer. would require a large assortment of springs, as to length and temper, to apply to the several Weights to be counteracted and to the exact length required, besides the necessity for a new spring whenever the spring attached should lose a portion of itsV elastic force.

When manufacturingloungesembodyingthe improvements described in Letters Patent No. 169,978, I can form the arm D-solid with the foot-end arm C. f

Devices for adjusting the elastic force of spiral springs are manifold, and therefore I do not wish to be restricted to the particular de- Tice herein specied.
